Show inherited signals in trap -p output

Description of problem:
trap -p doesn't show ignored signals inherited from its parent across an execve

Version-Release number of selected component (if applicable):
bash-4.1.2-3.fc14

How reproducible:
Always

Steps to Reproduce:
1. trap '' SIGINT
2. exec bash
3. trap -p
  
Actual results:
Nothing is returned as output of trap -p. But at the same time, running cat and trying to interrupt it shows that the signal is in fact being ignored

Expected results:
The list of ignored signals should be returned

Additional info:
Attached patch ensures that inherited ignored signals are reflected in trap_list and then subsequently displayed when trap -p is invoked.

It's not a bug, it's a feature:

So this is how it feels to close my own bug report as NOTABUG ;)
